A CORPORATION 01" NEW "WINDING DEVICE FOR TALKING MACHINES.

Application filed March 18,1927, Serial No.

This invention relates to improvements in talking machines and in particular to improvements in the means tor winding the spring; motors 'thereot. y

lln talking machines otthe smaller type, such tor example as portable talking machines, it is desirable that the machine as a whole should be as light "as possible and that it should be of a convenient size and shape. in a portable machine in particular it isdesirable that the machine should be 0t small height approximating to the shape oil an. attache *ase, so that it can be easily carried.

When. the motor of a machine of this type has to be wound up and the winding key is inserted horizimtally at the side or front oil" the machine, either the machine must be brought to the eiilge ot the table or other support on which it in order that the key may be turned, or else the winding key must have a very short crank so that the handle of the key does not strike the table, and a short crank makes winding diilicult.

r'tccording to the present invention the motor is so constructed that the winding key is inserted not horizontally but pointing obliquely downwards. This has the advantage that additional room is given for the handle oi. the key to be turned and has the Further :nlwintage that the machine is pr ssed slightly downiwuos-z on to its support and the machine less inclined to move about on its support as the winding key is turned. The winding key socket with which the key is engaged is mounted to lie obliquely to the top plate of the motor and this socket may be in one piece with. the worm member which engages a worm wheel mounted on the arbour ot the driving spring.

'llhe invention is illustrated. by way of eX- ample in the accompanying drawings in which,

Fig. 1 is a plan view at part of a portable talking machine to which the invention has been applied, the turntable, motor board and motor top plate being shown partly cut away for the sake of clearness.

Fig. 2 is an end elevation on the line ill-13 at Fig. 1, the winding key being shown in position.

Fig. 3 is a view on an enlarged scale of the member engaged by the winding key, and

Fig. l is a view also on. an enlarged scale 176,519, and in Great Britain April 9, 19536.

of the bearinp; for the member shown in Fig.

ldeiterring to the drawings 1 is the usual casing, 2 the motor board. and 3 the motor suspended from. the motor board 2 by suitable bolts t. The motor 3 is adapted to lie horizontally in the machine in the usual way and in the case illustrated the amplifying horn 5 encircles the motor. The horinontal top plate (3 of the motor has termed 1n 1t, an inverted channel portion '1 running" obliquely downwards trom the outside (see I' llg. 4:)- i

l Vithin this channel is secured a barrel 8 by means oil rivets 9 for example. The barrel is adapted to form a bearing for acombined winding key socket and worn]- member 10. The member 10 is furnished at one end with a threaded recess ll. torreception of the end of the winding key 12 and at the other end with a worm screw 13 which 'en gages with a worm wheel 14; on the arbor The worm threads on the member. 10 may conveniently be six in. number and they engage the worm wheel l t through a horizontal slot 16 in the side of the barrel lhe end of the member 10 is of reduced section and extends through an aperture in the end of the barrel 8 and it is secured in position by the insertion ot a spring rinn; 17 in a shallow annular recess 18 in the end of member 10.

Between the larger end oi memliier 1.0 and the interior surface oi? the barrel is coiled a s nking 19 one end ot which passes through an aperture in and anchored to the barrel 8 by a screw 20. This coil spring; 19 when the winding key 12 is turned in the motor winding direction slightly unwinds to permit tree rotation of the key but when the key is released the spring 19 tightens around it and holds it fast against rotation in the reversed direction.

The spring 19 fits sutliciently closely around the outer end of member 10 and within the barrel 8 to form a bearing for the outer end of the shaft.

The spring drum 21 may be mounted in the ordinary manner between the top and bottom plates (5 and 22 of the motor 3 the spring arbour 23 lying vertically, and the worm wheel 1% thereon horizontally.

The winding key may oi. course engage with the member 10 in any known or suitspr in I I able manner other than by its threaded end engaging the threaded recess 11..

By these means a light and inexpensive motor can be provided, with a winding key that can be inserted pointing obliquely .downwards from the side of the machine. In the side of the machine is provided the usual aperture or slot 24 for the key 12 to be passed through to engage with the key socket 11.

.I claim:

1. In a talking machine, a spring motor, a casing surrounding the motor, and a wind ing'shaft for the motor journaled near the top of'the casing and extending obliquely downward to the motor.

2. In atalking machine, a spring motor comprising end plates and a spring arbor mounted therein, a bearing in one end plate extending obliquely .toward the spring arbor, and a winding shaft for the spring arbor mounted in said bearing.

3. In a talking machine, a spring motor comprising top and bottom plates and a spring arbor mounted therein, abearing in the top plate extending obliquely downward toward the spring arbor, and a winding shaft mounted in said bearing.

4. In a talking machine, a spring motor comprising top and bottom plates and a spring arbor mounted therein, a hearing in the top plate extending obliquely down ward toward the spring arbor, a winding shaft mounted in said bearing, and gearing connecting the winding shaft with the spring arbor.

5. In a talking machine, a spring motor comprising top and bottom plates and a spring arbor mounted therein, said top plate having an oblique channel therethrough, a bearing mounted in said channel and extending adjacent the spring arbor, a winding shaft in said bearing and gearing connecting said shaft and arbor.

6. A portable talking machine comprising a cabinet, a spring motor therein, a winding key for'the motor having a crank throw atleast equal to the height of the cabinet, and a mounting connection for the key arranged oblique to the cabinet so that the handle of the key never extends below the bottom of the cabinet.

7. A portable talking machine comprising a cabinet, :1 spring motor therein, a winding key for the motor having a crank throw at. least equal to the height of the cabinet, and a mounting connection for the key arranged. so that the shank of the key extends obliquely downward through the side of the cabinet at such an angle that the handle of the key is always above the level of the bottom of the cabinet.

In testimony whereof I have signed my name to this specification.
